BUTTER-JAR.

SPECIFICATION forming part of Letters Patent No. 269,005, dated December 12, 1852. Application madam-mousse. (No monti.)

llo all whom 'it may concern Be it known that we, JoHN J osEPE CAREY and PATRICK CAvANAUeH, both of La Salle, in the county of La Salle and State of Illinois, have invented a new and Improved Butter- Jar, of which the followingis a full, clear, and exact description.

The object of our invention is to provide a new and improved vesselfor packing butter in such a manner that it will remain fresh and i sweet, and will be protected from the action of the air.

The invention consists in a jar provided with anl inner and outer cover, resting on packingrings and held on thejar by means of clamps passed over a circular ridge on the outer cover, which clamps are provided in their lower hooks with rubber blocks, resting with their upperedges against the lower edge of an external collar of the jar, which collar is provided with beveledV recesses. By moving these clamps out ofthe recesses and along the edge ofthe collar the outer cover will be held and pressed on thejar and its packing-rings.

Reference is to be had to the accompanying drawings, forming a part of this specication, in which similarletters ofreferenceindicate corresponding parts in all the figures.

Figure l is a side elevation of our improved butter-jar, the lower parts being broken off. Fig. 2 is a longitudinal sectional elevation of the samev on the line m x, Fig. l. Fig. 3 is a detail perspective viewot'one of the clampsfor holding the external cover ou thejar.

Thejar A, made of glass or earthenware, is provided at its top with an interior annular shoulder, a, upon which the inner cover or lid, B, is adapted to rest. Above this shoulder a the jar is provided with an interior shoulder, b, of greater diameter, which is flush with the upper edge of the inner cover, B. A flat packing-rin g, C, ot' rubber, leather, felt, or other suitable material, is placed on this shoulder b and on the edge of thelid B to cover thejoint of the lid and shoulder. A packing-ring, D, of rubber, leather, or felt, is placed on the upper edge of the jarA, and on this packingringD -the exterior cover, E, of the jar'is placed, this cover E being provided with an annular recess, so that an annular rid ge, d, which rests against the inner surface of the top of thejar, will be formed on Vthe under surface of the cover E. This cover E is provided ou its upper surface with a circular ridge, F, along the edge. The jar is provided at its upper edge with an eXterior collar, G, which is provided with beveled recesses H in its lower edge.

For the purpose of securing the cover E in place, we employ two clam ps--one pivoted and the other-rigid.

Two liat hooks, J J2, are pivoted to each other to form the pivoted clamp J, and the rigid clamp is formed of a strip of metal, having its ends bent over in the shape of hooks to form a clamping-clip, K.

The butter having been placed into the jar A, thecover B is placed on the same. The packing-ring Gis placed ou this cover, andthe packing-ring D on the upper edge of the jar, and then the cover E is placed on thejar. Strips or blocks L of rubber are placed in the lower hooks or pockets of the clamps J and K to form an elastic bearing against the shoulder b. rlhe upper hooks of the clamps J and K arelpassed over the ridge Fg, and the rubber strip L of these clamps J and Krests against the edge of the recesses H at their'deepest parts. By pushing the clamps J K partly around the cover E in the direction of the arrow ct the upper edges of the rubbersL of the clamps J and K pass along the inclined edge of the recess, and'i'rom there along the lower edge of the collar G. The upper hook of the clamps J and K will thus be pressed ou the ridge F, and will press the cover E on the upper edge of the jar, thereby closing this jar absolutely air-tight, whereby the butter will be protected from the action of the air, and will remain fresh and sweet.

The cover can easily be removed if the clam ps J and K are pushed back in the reverse direction of the arrow a.

Two clamps J or two clamps K may be u sed in place of-one of each kind, as shown; butwe prefer to use a pivoted and rigid clamp, the former being more readily manipulated than the latter.

Having thus described our invention, we claim as new and desire to secure by Letters Patenty 1. The combination, with the jar A, of the inner cover, B, the exterior cover, E, and the Ioo I hook-ended clamps J and K, substantially as herein shown and described, and for the purpose set forth.

2. The combination, With'thejar A, provided with the shoulders a and b, ot' the interior cover, B, the exterior cover, E, the clamps J K, and the packing-rings C D, substantially as herein shown and described, and for the purpose set forth.

3. The combination, with thejar A, provided with the shoulders a and b, and the external collar, Gr, havingr beveled recesses H, of the interior cover, B, the exterior cover, E, and the clamps J and K, substantially as herein shown and described, and for the purpose set forth.

A4. The combination, with thejar A, provided With an exterior collar, G, provided With beveled recesses H, of the interior cover, B, the exterior cover E, the clamps J and K, and the rubber strips or blocks L in the lower hooks ofthe clamps, substantially as herein shown and described, and for the purpose set forth.

5. rI`he combination, with the jar A, provided with an exterior collar, G, haviiugr recesses H in its lower edge, of the covers B and E, the clamps J and K, the clamp J formed ot' two pivoted hooks, Jl J2, and of the rubber blocks L, substantially as herein shown and described, and for the purpose set lforth.
